    • A polymeric material from the styrene family, consisting of macromolecular chains grafted by nitrogen-containing heterocyclic groups, wherein the macromolecular chains consist of a polymeric backbone to which a grafting agent is attached by at least one covalent bond, the grafting agent comprises, in a single molecule, one or more associative groups capable of being bound by hydrogen bonds, and one or more reactive groups capable of forming covalent bonds with the polymeric backbone, at least one of the associative groups of the modifier is an imidazolidone heterocyclic ring. The mean number of imidazolidone groups to be inserted into the macromolecular chains is dependent both on the mean mass of said chains and on the final properties to be imparted to the material. The polymeric material of the invention can be extruded, co-extruded, injected, blow-moulded, moulded, overmoulded, calendered, or thermoformed. Objects such as tubes, films, plates, stiffeners, bottles and containers can be made. The polymeric material of the invention can also be blended with other materials such as other polymers, and can thus be modified by elastomeric phases that enhance the impact strength thereof. The polymeric material of the invention can be a component of masterbatches of additives such as pigments and fillers. The present invention further relates to the use of said polymeric material as a compatibilisation agent in a composition including, inter alia, at least two polymers belonging to different polymeric classes.
    • 由苯乙烯家族组成的聚合物材料,由含氮杂环基团接枝的大分子链组成,其中大分子链由接枝剂通过至少一个共价键连接的聚合物主链组成,接枝剂包括 单分子,能够被氢键结合的一个或多个缔合基团和一个或多个能够与聚合物主链形成共价键的反应性基团,改性剂的至少一个缔合基团是咪唑烷酮杂环。 插入大分子链中的咪唑烷酮基团的平均数目取决于所述链的平均质量和赋予材料的最终性能。 本发明的聚合物材料可以挤出,共挤出,注射,吹塑,模制,包覆成型,压延或热成型。 可以制造诸如管,膜,板,加强件,瓶和容器的物体。 本发明的聚合物材料还可以与其它材料如其它聚合物共混,并且因此可以通过增强其冲击强度的弹性体相改性。 本发明的聚合物材料可以是颜料和填料等添加剂母料的成分。 本发明还涉及所述聚合物材料在组合物中作为相容剂的用途,所述组合物尤其包括属于不同聚合物类别的至少两种聚合物。
